Technical field
The utility model relates to a kind of isolation and amplifier module, particularly relates to and utilizes optocoupler to substitute isolated gate, a kind of light-coupled isolation output module of intrinsically safe circuit and non-intrinsically safe circuit being kept apart.
Background technology
Be with isolated gate, intrinsically safe circuit and non-intrinsically safe circuit are kept apart in present mine hoisting system, to avoid producing electric spark, guarantee the electrical safety at dangerous situations such as collieries.But because isolated gate volume is large, therefore take up room large, and price is high.
Summary of the invention
The purpose of this utility model is to solve the problem, and a kind of cumulative volume provided is little, occupy little space, use safety is easy, modularization, structuring, intrinsically safe circuit and non-intrinsically safe circuit can be kept apart, avoid producing electric spark, guarantee the light-coupled isolation output module at dangerous situation electrical safeties such as collieries.
Technical solution of the present utility model is: on the input of optocoupler U1, be parallel with resistance R2, resistance R2 connects with resistance R1 with after the input parallel connection of optocoupler U1, the output plus terminal of optocoupler U1 connects the collector electrode of triode V1 by resistance R3, the output negative terminal of optocoupler U1 connects the base stage of triode V1 by resistance R4, between the output negative terminal and the emitter of triode V1 of optocoupler U1, be parallel with resistance R5.
The utility model is arranged on the operating desk of Underground Mine system when using, and can replace multiple isolated gate; Intrinsically safe circuit and non-intrinsically safe circuit can be kept apart by the utility model, avoid producing electric spark, guarantee the electrical safety at dangerous situations such as collieries, input and output all reach 16 tunnels, and cumulative volume is little, occupy little space, use safety is easy, modularization, structuring, use Phoenix interface generality, compatibility strong, be adapted in other product designs general.
Accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, light-coupled isolation output module of the present utility model forms primarily of resistance R2, R3, R4, R5, optocoupler U1, triode V1, and module of the present utility model is powered by direct current 12V, 24V; The input of optocoupler U1 is parallel with resistance R2, and resistance R2 connects with resistance R1 with contact one end of the input parallel connection of optocoupler U1, another termination+12V DC power supply; The output plus terminal of optocoupler U1 connects the collector electrode of triode V1 by resistance R3, its tie point OUT1 is output signal point, and this output plus terminal of optocoupler U1 is connected with+24V DC power supply; The output negative terminal of optocoupler U1 connects the base stage of triode V1 by resistance R4, between the output negative terminal and the emitter of triode V1 of optocoupler U1, be parallel with resistance R5, the also interface VGMD ground connection of resistance R5 and triode V1 emitter; The utility model can be made up of 16 identical foregoing circuits, makes input and output all reach 16 tunnels.
Operation principle: module of the present utility model is that input side direct current 12V powers, the 12V voltage of an input part is provided required voltage for opening of optocoupler input side by resistance R2.Non-intrinsic safety signal and intrinsic safety signal are kept apart by optocoupler U1, to guarantee the safety of circuit.Outlet side is that direct current 24V powers, and when optocoupler U1 does not open, outlet side point position OUT1 is 24V; When optocoupler U1 opens, triode V1 conducting, drags down output point position OUT1 voltage as 0V.Export side joint+24V and OUT1, these two some positions are the input point of required access device below.
Claims (1)
1. a light-coupled isolation output module, it is characterized in that: on the input of optocoupler U1, be parallel with resistance R2, resistance R2 connects with resistance R1 with after the input parallel connection of optocoupler U1, the output plus terminal of optocoupler U1 connects the collector electrode of triode V1 by resistance R3, the output negative terminal of optocoupler U1 connects the base stage of triode V1 by resistance R4, between the output negative terminal and the emitter of triode V1 of optocoupler U1, be parallel with resistance R5.
